TYPE FOR PRINTING LAMP-SHADES.

SPECIFICATION forming part of Letters Patent No. 453,771, dated June 9, 1891.

Application filed August 20, 1890. $erial No. 362,497. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS HARPER, a citizen of the United States, and a resident of lVestchester, in the county of Vestchester and State of New York, have invented certain new and usef ullmprovements in Type for Printing Lamp-Shades and Analogous Articles, of which the following isa specification.

The object of my improvement is to provide simple and inexpensive type which will present a substantially flat surface for inking and will yield to adapt itself to the convexity of alamp-shade or like article.

I will describe type embodying my improvement, and then point out the novel features in a claim.

In the accompanying drawings, Figure 1 is a face view of a type embodying my improvement. Fig. 2 is a side view thereof, looking in the direction indicated by the arrow a", which is marked adjacent to Fig. 1. Fig. 3 is a side view looking in the direction indicated by the arrow p, which is marked adjacent to Fig. 1. Fig. at is a front view of a type of modified construction. Fig. 5 is a side view looking in the direction indicated by the arrow :10, which is marked adjacent to Fig. 4. Fig. 6 is a side view looking in the direction indicated by the arrow p, which is marked adjacent to Fig. 4:. v

Similar letters of reference designate corresponding parts in all the figures.

I will first describe that example of my improvement which is illustrated by Figs. 1, 2, and

A designates a printin -surface consisting of a sheet of rubber, rubber cloth, or like flexible material, cut to represent any desired article.

B designates a support comprising a number of strips of spring metal b, arranged at short distances apart, so as to be parallel to each other, and having the end portions bent downward and inward and then downward and outward. The extremities of these strips are fastened by solder or otherwise to rails c 0 forming part of a holder 0. The support B also comprises a number of strips of spring metal D which cross the strips 1) at right angles and are arranged at short distances apart parallel. to each other. The strips 1) are fastened midway between their ends to the center strip 1). \Vhile they maybe fastened in any desired manner, I prefer to fasten them in place by riveting. I desire it to be understood that the strips Z) are entirely disconnected from each other, that the strips b are entirely disconnected from each other, and that the strips b are unconnected with any of the strips 1), saving only the center strip of that series.

Owing to the described construction of the support 1), it is free to bend in all directions to conform to the convexity of a lamp-shade or similar article. The printing-surface is not connected throughout its extent to the support B, but preferably is only connected thereto at its center. It may be fastened by cement, as s, to the center strip 11 \Vhen so connected, it and the support B can together adapt themselves to convex surfaces.

The resilience of the support B will keep it flat during inking and yet allow it to yield, as may be necessary, in printing.

The holder 0 is provided with a socket D, having a longitudinal opening at one side, so as to be capable of expansion and contraction. Adjacent to the opening this socket is pro vided with lugs 61' (1 A screw passing through the lug (Z and engaging with a tapped hole in the lug (Z affords provision for tightening the socket. The socket is intended to fit an arm in a printing-press.

In Figs. at, 5, and G I have illustrated a very similar construction, substantially the only difference being that the strips b of Figs. 1, 2, and 8 are entirely omitted, and instead of the flat strips Z) round strips or wires 1) are used. These wires are bent longitudinally just like the strips Z) in Figs. 1, 2, and 3, and are at the ends soldered to the rails c c of the hold er 0. The printing-s11 rface A is attached at its center by cement, as at s, or by any other means to one or more of the wires.

The type last described, like the one represeted in Figs. 1, 2, and 3, will present a fiat surface for inking and can yield in printing to conform to a convex surface.

In each example of the improvement the surface of the support Bis much larger than the printing-surface A. The particular printing-surface represented is a small one. The

2. A type having a flexible printing-surface and a support therefor, consisting of a number of parallel strips which are of themselves resilient, substantially as specified.

3. A type havinga flexible printing-surface and a support therefor, consisting of a number of strips which are of themselves resilient, bent inward and outward at their extremities, substantially as specified.

4 A type having, a flexible printing-surface and a support therefor, consisting of a series of parallel strips fastened at the ends and a second series of strips extending at right angles to the first series and fastened at the middle to one of the first series of strips, substantially as specified.

Signed at New York, in the county of New York and State of New York, this 12th day of May, A. D. 1890.

THOMAS HARPER.
